1. When ordering, please specify termination and packaging codes:
MLC1770-282MEC Termination: E = RoHS compliant tin-silver over copper
Special order, added cost: T = RoHS tin-silvercopper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D = 13″ machine-ready reel. EIA‑481 embossed plastic tape (400 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4263B LCR meter. 3. SRF measured using an Agilent/HP4291A impedance analyzer and an Agilent/HP 16193 fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C am...
